Dion felt a the tingle start with his head.
Excitedly, he ran to the mirror to see what was happening. He noted his light hair slowly getting darker, while his earrings fell out of his ears and faded into nothing. His lashes seemed a bit shorter. As his hair was turning into his original brown, he noted his bib-overalls hadn't changed yet. His shoes changed from a pink unicorn nike to ones with transformers. His socks lost their ruffles. They were boy jeans! It looked like the changes started from the top and bottom.
His room started to change at this point, the wall colors, posters and furniture started to look more like a boys room. He started to walk around the room while holding the medallion, enjoying the familiarity of it all.
Dion was so entranced by the changes of his room, he didn't notice he was getting a little taller. He also did notice the stuff that appeared on his floor, until it was too late. He tripped over a toy truck on the floor. When he hit the ground and his head hit the floor, he let go of the medallion and the jeans.
The tingle stopped.
Getting up, Dion rubbed his head. When it looked around, he saw his room was just about back to the way it was. Except, there were a few more bits of electronics, and his posters were for cartoons that his mother thought were too old for him. He got up and and looked in the mirror.
His clothing was not longer overalls. He was wearing a white teeshirt and shorts. The jeans did have a hole in the knee. He looked about 1-2 years older. He then noted his tee-shirt. No bumps. He lifted his shirt, and noted he looked like a boy there. Holly had started to have girl parts there when she was about 12.
"Yes!" said Dion as he jumped up and down "The curse is lifted! Now to get back at Holly..."
After a couple hours of consideration of how to get back at her, Dion needed to use the restroom. He went down the hall, closed the door, and reached to pull out his man parts...only to find he still did not have them!
